LR44 Alkaline Coin for Wire Tracker - Wire Tracer - signal generator

[Kiriakos GR]

I do not buy frequently LR44 Alkaline Coin cells.

But I am after to stock some cells for my Sperry ET64220.
All such Wire Tracer designed for portability, they use LR44  at receiver hand-piece.

I did find a good deal of unbranded LR44 at local store, pack of four = 0.60 €.

Then I thought to look of what I am missing by skipping Toshiba cells, this time?

energenie EU importer 
Net weight: 1.86 g
Nominal voltage: 1.5 V DC
Nominal capacity: 150 mAh (at 20 °C temperature, up to 0.9 V voltage)

From the side of Toshiba
Approx. service capacity: 158 mAh   
When in another document it mention 148 mAh

At the year 2025, it might be an idiotic thought, looking for best LR44 Alkaline Coin within official imposts in European Union.
Chances of getting bad quality or DOA, these are very few.
From the other hand any Asian ODM, involved at the manufacturing of Alkaline, he use modern facilities, and tools.

So the only detail that we should wonder,  this is of how sincere is the evaluation of the expiration date?

Best advice for any one who use such testers infrequently, this is not having any battery cells installed.
Keep these Alkaline Coin at factory packaging, stored with the tool.
Install them only when needed.     

My Sperry ET64220, this also require a pair of AAA for the transmitter.
For that side, I have a preference over Toshiba HIGH POWER for more than 10 years.
